To all whom it nwz/omw w part at predetermined times movements of Beitknown that I, HOWARD K.

This shaft, through suitablecrated upon, and mechanism adapted to imcams and connections hereinafterdescribed,

operates all the movable parts of the .machine. It is driven by a belt(not shown) running over a pulley 3 on the end of a shaft 4, hereinafterreferred to as the drivingshaft, also journaled in the frame and havingon its other end a pinion 5, whose teeth engage those of a spur-wheel 6on the camshaft 2. I usually mount a hand or fly wheel 7 upon thedriving-shaft.

8 represents the mold-boxes (two in number in this instance) in a commonpartitioned frame 9, which are lined with hardened steel and whose endsmay, if desired, be chambered out for steam-heating.

10 represents the plungers, that are fitted to and adapted to workvertically in the moldboxes.

11 represents T-shaped stationary anvils, as I shall term them, uponwhich the clot-s to be compressed are supported and upon which they arepressed by the plungers. These anvils rest upon an arched diaphragm 1 ofthe frame, and although I term them anvils they may be said to bestationary plungers, as they are in length and breadth but slightly lessthan the corresponding dimensions of the respective mold-boxes, so thatthe latter may in their descent pass below and closely adjacent to thesides of the anvils.

The necessary downward movement is imparted to the plungers 10 at theproper intervals as follows: The upper end of each of the plunger-rods10 is secured to the lower limb 12 of a cross-head 12, that is adaptedto slide vertically in guideways 13 of. inward projections 1 of theframe. The upper part of said cross-head has a transversehorizontally-rotatable shaft 14, to which are secured I connecting-rods15, whose upper ends are secured to a similar rotatable shaft 16 of acrank-head 17, that has laterally-projecting studs 13, which arejournaled in bearings of the posts of the frame of the machine. Theshaft 14 and studs 18 are substantially in line vertically. Fixed to thecrank-head 17 at an angle to the limbs of the former is an arm 19, whichhas a roller 20 at its free end that is adapted to ride on the face of acam 21 of the form shown in Figs. 1, 5, and 10 on the camshaft 2.Secured to lateral extensions of the mold-box frame are vertical rods22, whose upper ends are respectively pivotally connected to the lowercross-head 23" of a link 23, whose upper cross-head 23 is pivoted on theend of an arm 24 of a rock-shaft 25, Figs. 1 and 3, journaled in themain frame. On the latter shaft is also mounted a forked arm 26, theupper limb 26 of which carries at its free end a roller 26 that isadapted to ride 011 a cam 27 on the cam-shaft 2, and its lower limb 26has a roller 26, that is adapted to ride on a cam 28, also on saidcam-shaft. These cams are of the forms respectively shown partly in fulland partly in dotted lines in Fig. 5 and seen in edge elevation inFig. 1. The cam 28 operates to depress the mold-box and the cam 27toraise the same at certain intervals and for purposes as here inafterexplained. The cam 21 in its rotation serves only to depress the arm 19of the crank-head 17,and consequently the plungers. In order to raisethe plungers,I suspend a heavy weight 29 (indicated in dotted lines inFigs. 1 and 5) from the end of an arm 30 upon the projected end of oneof the studs 18 of the crank-head 17. As, however, when the clot of clayhas been re-pressed or molded a considerable force is required toretract the plunger, or rather to give it a start, I provide on the sideof the plunger-cam 21 a cam ledge or projection 31', Fig. 1, (shown alsoin dotted lines in Figs. 5] and 10,) against which is adapted to ride atcertain times in the rotation of cam 21 a roller 32, that is journaledon a lug 30 of the arm 19.

33 represents fixed plates or tables that are boxes.

Between and below the line of the top of the anvils and the tables 33extends a horizontal bar 35, which I term the feed-bar, on one end ofwhich is a cross-bar 35 at right angles to the latter, like the head-barof a T- squa re, and projecting above the plane of the tables, as shown.The other end of the bar 35 is secured to and beneath the horizontallimb 36 of a gooseneck 36, and on the top of the gooseneck is fixed ahorizontal plate 37, hereinafter termed the off-bearing plate, that is ashort distance above the line of the anvils and whose inner end isupturned to form a flange 37, whose front edge is at right angles to thetop of the plate, and its lower edge is beveled, as shown. The verticallimb 36 of the gooseneck is provided with flanges 36, that are fitted toand adapted to slide horizontally in guideways 36 of supportingbraekets36 fixed to a part of the main frame. (Seen most clearly in Fig. 1.) Thelower end of the gooseneck is pivotally connected by a rod 38 to an arm39 of a rockshaft 40, that is journaled in bearings of the lower part ofthe frame 1. On the outer end of this rock-shaft is a crank-arm 41, tothe free end of which is pivoted a vertically-extending rod 42, whoseupper end is pivoted to the lower limb 43 of a bell-crank 43, that isjournaled on a stud 43 that is fixed to and projecting from the side ofthe frame. The upper arm 43 of the bell-crank has on its free end aroller 43, that is entered in a cam-groove 44 in the face of a cam-wheel44*, Figs. 1 and 4, on the camshaft.

The anvils have vertical vent holes 45 therein of comparatively-smalldiameter, preferably located as shown more clearly in Fig. 7, and whosepurpose is to permit the escape of a certain quantity or excess of theclay during the process of pressing the clots in order to avoidliability of fracture of the machine and also in order that thesuccessive bricks may be of-uniform size. In order, however, to obviatethe escape of too great a quantity of the clay through said holes, Iprovide a mechanism for at the proper times cutting off the outflow.This cutting-off mechanism is as follows: Below the vent-holes of theanvils and adjacent to their neck are two similar rock-shafts 46 46,that are journaled in the main frame and extend transversely to theanvils. On the end of one of the shafts, 46, is an arm 47, with teeth onits free end that are in engagement with the teeth of a similar arm 47on the other shaft, 46. Pivoted to a part or extension of the latter armis a connecting-rod 48, whose upper end is pivoted to the end of an arm49 of a bell-crank 49, that is journaled on a stud 49 projecting fromthe side of the main frame. The other arm 49 of the bellcrank carries atits free end a roller 49 which is entered into a cam-groove 50 in theside of a cam-wheel 50, that is mounted on the cam-shaft, as shown inFigs. 1 and 2. The configuration of this groove is most clearly shown bydotted lines in Fig. 2. Secured to the rock-shafts 46 46*, or rather toarms 46 thereof, are pins 51, whose upper ends are in such proximity tothe line of the lower ends of the vent-holes 45 that when the pins arerocked outwardly they will cut off the noodles or small stems of claythat have been forced through said holes and will also close the latterat predetermined times, as and for a purpose hereinafter explained.

Having now described the construction of the machine (not going intominor details or describing parts tending to render the operation moreperfect, which parts will be hereinafter described) and premising thatthe said several cams carried by the cam-shaft 2 are so shaped and timedas to effect at the proper instants or intervals the movements of therespective parts actuated thereby, I shall now proceed to explain theoperation of the machine,as follows: The clots to be repressed, whoselength and width are less than those of the interior of the mold-boxes,are placed upon the tables against the sides, respectively, of theguide-bar 34 at the time when the feed-bar has been projected to itsfarthest outward extent by operation of the cam 44 and its connectionswith the rock-shaft 40-that is to say, when the crossbar 35 is at theouter end of the tables 33, as seen in Figs. 15 and 16, Sheet 7. Thelatter figure bar 34 just after the re-pressing of the previous clot.Now as the cam-wheel 44 continues to rotate, and thus actuates therockshaft 40 through the connecting-rod 38, &c., the gooseneck slidesforward, and the crossbar 35", impinging against the rear end of theclot O, carries the latter into position upon the anvil ll, beneath themold-box. As, however, the momentum is liable to carry the clot too far,and thus out of register with the mold-box, I provide a means forarresting the clot when it arrives at the required position. Thisconsists in the present instance of a bent or approximately U-shapedspring 52, whose lower limb 52 is fastened to a bracket 53, that issecured to the top of the anvilsupporting diaphragm, and whose upperlimb 52 extends above the plane of the anvil and its inner side is inline vertically with the inner edge of the mold-box on that side. Thetiming of the mechanism which actuates the feed-bar is such that whenthe bar has reached substantially the limit of its forward movement theclot G will impinge against the spring-stop 52. As the cross-bar 35 isthen directly beneath-that is, in the path of-the forward wall of themold-box, as in Fig. 11, it is necessary that it should be gotten out ofthe way before the box shall descend to incase the clot. \Vhen the saidbar is at the limit of its forward throw, the roller 43 is riding in therounded portion or swell (marked 44 Fig. 4) of the cam-groove 44, and asthe cam-wheel continues to rotate the said roller enters the depressionat 44 of the said canigroove, and a slight rock is thereby imparted tothe shaft 40, which carries back the feedbar a short distancesufficiently to cause its cross-bar 35 to amply clear the line of themold-box-that is, from the position of Fig. 11 to that of Figs. 12, 13,and 14, Sheet 7. The bar remains in this position until roller 43 passesfrom the semicircular part 44 and comes to the part 44 of the cam-groove44. The mold-box now descends by the action of the rotating cam 28 uponthe roller 26 of the lower limb 26 of forked arm 26, as in Fig. 12, andcontinues its descent, finally incasing the clot C, as seen in Fig. 13,the stopspring being at the same time depressed by the mold-box. Theplunger 10 is now forced down by the cam 21, and thus the clot iscompressed upon the anvil. Any excess of clay is forced through thevent-holes 45; but just before the final pressure is givenby the plungerthe pins 51 are rocked outwardly by the action of the suitably-timedcarngroove 50, in the high part 50", Fig. 2, of which rides the roller49 of the bell-crank arm 49", that is connected by the rod 48 with thetoothed arm 47 upon the shaft 46 upon which latter said pins aremounted, as before described. These pins break off the noodles and stopthe flow of clay through the vent-holes. As the cam 21 continues itsrotation and the roller 20 rides 011 the highest point of the cam, as inFig. 10, the final pres- IIO 5 sure is given'to the clot by the plungerswhile the said holes are thus closed. This latter pressure while notwholly essential is designed to impart a uniform texture to theclay-that is, to compact that part of the clot at or about the pointswhence the clay has flowed through the vent-holes. The mold-box andplunger now being in the position shown in Fig. 13 rise thence to thatof Fig. 14, the mold-box ascending through the action of cam 27 and theplunger by the weight suspended from the arm 30 of stud 18, it (theplunger) being, however, started by the positive action of the cam-ledge31 of the cam 21 impinging against the roller 32 on arm 19, so as toovercome the suction of the clot to the anvil, as seen in Fig. 10. Whileat this time the plunger has reached its upward limit, the mold-box,still incasing the clot, (which has been carried up from the anvil bythe box,) has, for a purpose hereinafter appearing, not reached itshighest point. At this juncture-that is, after the box and plunger haveascended, as seen in Fig. l t-the feed-bar 35 is retracted by meansofthe before-described mechanism, suitably timed for actuating it, fromthe position seen in Fig. 14, also in Figs. 12 and 13, to that of Figs.15 and 16that is to say, the off-bearing plate 37-is carried intoposition over the anvil and beneath the mold-box and the re-pressed clottherein, the lower beveled edge of said plate in its inward movementimpinging against and depressing the spring-stop 52 out of the way, orrather against an incline 52, Fig. 9, upon the spring. The cross-bar 35is also carried to the rear part of the table in position to slide thenext clot to be repressed from the table to the anvil. The mold-box isnow caused by its operating-cam 27 and connections to rise to itshighest limit, as seen in Fig. 16, the distance from the under side ofthe plunger to the top of the off-bearing plate being a little greaterthan the thickness of the clot that has been operated upon. This ascentof the mold-box freeing the clot therefrom causes or permits the latterto drop upon the off-bearing plate, by which it is carried forward intoconvenient position to be taken away by the attendant of the machine,when the feed-bar is again advanced to carry the succeeding clot intoposition beneath the mold-box, as in Fig. 11. In order to insure thedrop of the clot which may adhere to the plunger, I usually impart afinal down: ward movement to the latter by providing the .edge of thecam 21 with a projection 21, of substantially the form shown in Figs. '5and 10. This projection impinging against the roller 20 at the properinstant-that is, at the same time the mold-box is ascending to itshighest limit-gives a slight descent of the plunger and with it therepressed clot, thus positively delivering the latter to the off-bearingplate.

'from the upper roller.

In order to obviate the liability of sticking of the top and bottom ofthe clot, I apply oil or other lubricant to these surfaces of thelatter. This I do by the following means: 54:, Fig. 5, is a box or tankfor containing oil, in the bottom of which is a pipe 54 having a petcoek5t therein for allowing oil to fall or drip from said tank onto a roller55, covered with felt or the like and journaled in bearings of arms 56,that depend from the tank. Directly beneath this roller are two secondsimilar rollers 57, that are journaled in posts of a bracket 58, fixedto the frame of the machine, and whose peripheries are substantially inline with the tops ofthe tables 33, respectively. These rollers arelocated in advance of the line of the forward end of the tables 33 and ashort distance to the rear of the line of the mold-box frame. Thedistance between the said rollers is substantially the thickness of theclot to be operated upon and in order to adapt the rollers forvariations in the thickness of clots the bearings of the journals of theupper roller are vertically elongated, so that the roller may adaptitself to the clots. The lower rollers are supplied with oil by thedripping As the clot is carried between the rollers by the movement ofthe feed-bar its top and bottom will be oiled by coming into contactwith the peripheries of the rollers.

In order to adjust the relative height of the plunger for clots ofdifferent thickness, I connect it (the plunger) to the limb 12 of thecross-head 12 in the manner shown most clearly in Fig. 9, Sheet 6, asfollows: is a flanged tubular head which is secured to the top of theplunger 10 by means of bolts 60" and is internally screw-threaded toreceive a threaded bolt 60*, with a contracted stem that extends throughan aperture in the part 12, and is secured to the latter by means of anut 60 in the projecting end of the stem, whereby the bolt is clamped tothe cross-head, as shown. It will be obvious that byloosening the saidnut and turning the bolt the plunger may be brought toward or away fromthe cross-head to suit the thickness of the clots to be operated upon.As it may sometimes occur that the resistance of the clot tocompressionwill be such as to break or strain some part of the machineunder the heavy pressure, I usually insert between a shoulder 60 at thebottom of the stem of the bolt (30 and the under side of the part 12 ofthe cross-head 12 a safety-washer 61, composed of soft metal ormaterial, whose strength is sufficient to resist ordinary strains, butwhich will crush under abnormal pressure,and thus obviate fracture ofthe machine. The frame as well as all the parts of the machine are,however, made heavy and of great strength, having regard to economy ofspace.

The mold-boxes and vent-holes, as also all the parts of the machine thatcome in contact with the corners of the clot while pressure is beingapplied thereto, are preferably lined with hardened steel, as seen.

IVhile I have shown one way of carrying out myinvention, I do not wishto be understood as limiting myself to the precise constructions ormechanisms shown and hereinbefore described, as substantially-identicalresults may be attained with other mechanisms adapted to operate insubstantially the same way or upon the same essential principle.
